Abstract: THERMOSTAT AND IRON ASSEMBLY  ABSTRACT OF THE DISCLOSURE             In an electric steam iron with an enclosed water tank in a shell under a handle and a steam generating soleplate with steam distributing ports, a pump is connected to the tank with a handle button for pump actuation to deliver water to the soleplate generator. The soleplate provided with an elevated threaded boss or mount for close support of a heat-responsive miniature adjustable thermostat to control the soleplate temperature.  The thermostat includes a conductive intermediate stiff spring blade and a conductive upper less stiff spring blade with the  blades stacked, supported, secured, and spaced apart by a bolt-thru-a-rivet connection in a conventional manner at one end with interposed insulators and having electrical circuit contacts on the conductive blades to make and break the heating circuit for the soleplate. To this conventional overall iron structure an improvement is provided that comprises a lower heat deformable blade that is completely separate and spaced from the stacked blades and disposed below the riveted stack. An insulator transmits the heat deformable blade movement to the upper blade to make and break the contacts. The deformable blade is disposed in close contact on the soleplate mount above the soleplate and completely below the shaped rivet head at the lower end of the stack. An aperture through the heat deformable blade inner and accommodated the bolt connection to the threaded mount to secure the parts to the threaded mount. The interposed heat deformable separate blade is provided with a conforming shaped rim at its apertured end, preferably in a square fitting, for nesting alignment of the deformable blade with the stack.  The arrangement is such that the separate deformable blade is secured directly on the soleplate mount for fast heat response from the soleplate to eliminate the heat insulation effect by the rivet to reduce overshoot from extreme sensitivity of the miniature thermostat.

Abstract: TITLE PROCESS FOR THE RECOVERY OF CATALYST VALUES                       ABSTRACT OF THE DISCLOSURE Disclosed is a process for the recovery of catalyst values from a catalyst-tar solution derived from a production system in which acetic anhydride is prepared by carbonylating methyl acetate in the presence of rhodium, lithium and methyl iodide.  The catalyst values are recovered by submitting the catylist-tar solution to an extraction using methyl iodide And aqueous hydrogen iodide.  The presence of hydrogen iodide in the aqueous phase stabilizes the rhodium in water soluble form and thereby permits the aqueous phase containing the catylist values to be concentrated to remove most of the water prior to recycling to the carbonylation reactor.

Abstract: Abstract of the Disclosure A drainage device for drainage of moisture which collects between a water-proof isolating layer applied to the top surface and a concrete slab itself and/or moisture which passes through a surface layer deposited on top of the isolating layer.  The drainage device has a drainpipe extending through the concrete slab and having at its upper end a shallow funnel provided on its upper surface with radially extending grooves and being flush with the top surface of the concrete slab.  The funnel is fitted on its underside with a centering cuff concentrically surrounding the funnel tube spatially separating the funnel tube from the drainpipe, the diameter of the funnel tube being at least about 20% smaller than the inner diameter of the drainpipe.  The upper end of the funnel opening is covered with a mushroom shaped insert resting on the top of the isolating layer and having radially extending grooves on its underside.  The bottom end of the drainpipe has an outlet member supported in the concrete slab in such a manner as to be flush with the underside of the slab and has two concentric drip collars.  The drainage device of this invention reduces clogging due to accumulation of lime deposits and reduces long icicles forming at the outlets of such prior art drainpipes.

Abstract: FOAM COATING           ABSTRACT OF THE DISCLOSURE           Surface coating methods and apparatus are disclosed which eliminate many of the disadvantages  associated with known coating processes from pollution, equipment, materials, energy, labor and cost standpoints.  According to techniques described, liquid compositions containing film-forming solids are formulated then conveyed in the foam state towards a surface, and upon foam disintegration, form a film of solids on the surface.  The tech-niques disclosed eliminate the need for solvents in paints or reduce volatile content to very minimal amounts.  This method also enables polymeric compositions having high molecular weight to be employed as coating materials.  Furthermore, the method has utility in nearly all coating processes where the film-forming solids are conveyed from a bulk state to a surface for coating.
